日本橫河EJA115型微小流量變送器是一款內(nèi)藏孔板的差壓變送器，特別適用于測(cè)量微小流量，然后將其轉(zhuǎn)變成4-20mA DC的電流信號(hào)輸出。

日本橫河EJA115型微小流量變送器內(nèi)藏孔板有六種內(nèi)徑，范圍從0.508mm到6.350mm?？讖降倪x擇結(jié)合差壓變送器的差壓測(cè)量量程，就可進(jìn)行大量范圍的微小流量測(cè)量。
上海中豫科技有限公司提供的EJA變送器的特性

的性能和穩(wěn)定性

EJA系列采用單晶硅諧振式傳感技術(shù)。單晶硅對(duì)于壓力或溫度的變化不存在滯后現(xiàn)象，是非常理想的材料。單晶硅諧振式傳感器將過(guò)壓、溫度變化和靜壓影響降為zui低，從而提供的長(zhǎng)期穩(wěn)定性

小型輕量設(shè)計(jì)

由于采用ASIC放大器設(shè)計(jì)便包裝變小，以及膜盒構(gòu)造和法蘭的小型化，這款機(jī)型的重量降到了原有機(jī)型的一半。ASIC設(shè)計(jì)不僅減少了零件數(shù)量，而且提高了放大器的可靠性。

現(xiàn)場(chǎng)總線通信能力
現(xiàn)場(chǎng)總線是雙向數(shù)字通信系統(tǒng)，是配置儀表控制系統(tǒng)的革新技術(shù)，同時(shí)也是前景很好的更新?lián)Q代產(chǎn)品，用于替換現(xiàn)在現(xiàn)場(chǎng)儀表中廣泛使用的標(biāo)準(zhǔn)4-20mA模擬通信。
